Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: The LT3724 includes overtemperature protection that is intended

to protect the device during momentary overload conditions. Junction

temperature will exceed 125°C when overtemperature protection is active.

Continuous operation above the speciﬁed maximum operating junction

temperature may impair device reliability.

Note 3: The LT3724E is guaranteed to meet performance speciﬁcations

from 0°C to 125°C junction temperature. Speciﬁcations over the – 40°C

to 125°C operating junction temperature range are assured by design,

characterization and correlation with statistical process controls. The

LT3724I is guaranteed over the full –40°C to 125°C operating junction

temperature range. The LT3724MP is 100% tested and guaranteed over

the –55°C to 125°C operating junction temperature range.

Note 4: VIN voltages below the start-up threshold (7.5V) are only

supported when the VCC is externally driven above 6.5V.

Note 5: Operating range is dictated by MOSFET absolute maximum VGS.

Note 6: Supply current speciﬁcation does not include switch drive

currents. Actual supply currents will be higher.

Note 7: DC measurement of gate drive output “ON” voltage is typically

8.6V. Internal dynamic bootstrap operation yields typical gate “ON”

voltages of 9.8V during standard switching operation. Standard operation

gate “ON” voltage is not tested but guaranteed by design.

Note 8: The –1V absolute maximum on the SW pin is a transient condition.

It is guaranteed by design and not subject to test.
